mr_sifter writes: Intel is due to replace its mainstream CPUs with a new range at the end of the year, currently codenamed "Sandy Bridge." As well as being incompatible with current motherboards (by one pin!), a leaked presentation confirms the design of the motherboards may effectively kill off overclocking by using a very locked down clock generator. That is, unless, of course, you want to pay extra for a special K-series CPU, which will allow overclocking via the multiplier.
